Answer:
D) 10 units
Step-by-step explanation:
Opposite sides of a parallelogram are congruent.
__
<h3>setup</h3>
The relation between opposite sides tells you ...
BC = AD
2x = x +5
<h3>solution</h3>
x = 5 . . . . . . . subtract x from both sides of the equation
We want the length of AD, which is ...
AD = x +5 = 5 +5
AD = 10

<em>Additional comment</em>
Often, it seems like the question is answered once the value of x is found. Here, finding the value of x is an <em>intermediate step</em>. The value of x is needed in order to be able to answer the question about <em>the value of an expression involving x</em>.
Answer:
3 years
Step-by-step explanation:
In this problem, the initial number of students at time t = 0 is
We know that the number of students increases by 5 % every year. This means that we can write the student's population as
where
t is the time, measured in years
Here we want to find after how many years t the student's population will exceed the maximum capacity of the school, which is
N = 1100
To solve the problem, we just put n = 1100 and we solve for t. We find:
Which means that the student's population reaches the maximum capacity of the school after 2.37 years. Since we want this number to be an integer, this means that the enrollment will exceed the capacity in 3 years.

Answer:
45degrees
Step-by-step explanation:
The measure of angle WTV is 50°. The measure of angle STW is 95°. The measure of angle STV is x°. Find the value of x.
The expression is true for the angles
<STW = <WTV + <STV
<STV = <STW-<WTV
<STV = 95 - 50
<STV = 45degrees
Hence the measure of <STV is 45degrees
